September 2000 - In August, the Colorado Air Pollution Control Division (APCD) finalized a settlement with the largest electricity user in the state by which the company agrees to purchase approximately $300,000 worth of wind power for up to five years to offset a violation of air quality regulations. The state typically allows violators to offset up to 80% of a civil penalty by performing a Supplemental Environmental Project (SEP). In this case, the two parties agreed to a SEP in which the company will place funds into an escrow account to be managed by Public Service Company of Colorado (PSCo), which will be used to pay for power from the utility's WindSource program. The average annual purchase called for in the SEP is roughly equivalent to the annual output of one 750-kW wind turbine.
